Implementing runtime PM for PCI requires ensuring that device GPEs are
enabled for runtime. This is made awkward by the fact that multiple PCI
and ACPI devices may use the same GPE, so it's necessary to track how
many devices currently want the GPE to be enabled. This would seem to
imply some sort of refcounting, but I can't see an especially clean way
to implement this in the current code. Does anyone have any preferences
for what this interface should look like?
